Which risk increases for soaring birds during heavy molting resulting in primary feather loss?

💡 Explanation

When primary feathers are lost during molting, lift production is reduced due to decreased wing area because air travels easily throughout the missing feathers affecting camber and airfoil of wing. As such the flight becomes less aerodynamically efficient resulting in stability concerns. Therefore reduced aerodynamic control results, not infection, heightened metabolism or poor camouflage which involves different mechanisms.

• When a bony fish experiences buoyancy loss affecting its neutral swim, which mechanism will compensate to equilibrate depth?
• Which risk increases when asynchronous contraction limits air sac volume modulation during avian flight at high altitude?
• Which outcome increases when nitrogen fixation pathways are suppressed in legume root nodules?
• Which outcome occurs when the angular deviation displayed via waggle dance is misinterpreted in Apis mellifera?
• Which outcome occurs when constraints limit induced torpor?
• Which outcome hinders nutrient intake when transpiration is excessively slowed?
